It's a mate-on-mate space race — but which of your hosts has more star power? In this penultimate episode of Season 1, Jack and Justin put their space knowledge to the test as they compete for seats on the next flight to Mars.

Featuring guest vocals from Stuart Buckland as the Examiner, Sez O'Neill as the Spaceport Announcer, and the Robot Security Guard as himself.

ACKNOWLEDGEMENT OF COUNTRY: Mates in Space is made on Kaurna, Gadigal and Wurundjeri Country, never ceded. We pay respect to Elders past, present and emerging. We also pay respect to other First Nation peoples.

ABOUT US: Mates in Space is a podcast about how we’re going to get to space without taking all of Earth’s bulls**t up with us! Each week, your hosts Jack and Justin will tell a different space story, in preparation for Australia’s exciting new future among the stars. It’s a bit nerdy, a bit sciency, and a lot of fun.

Mates in Space is brought to you by Ampel Audio, Jack Eaton and Justin McArthur. For more info, check out our website at http://matesin.space
